An operating method for container quay cranes used to load and unload container ships aided by a PC with a monitor in a crane driver's cabin.The crane driver operates a touchscreen on the monitor, thereby enabling the crane to reach its specified target in a fully or partially automatic manner.Several operating modes, including a training mode, are provided.
摘要:
In a method of automating the loading and unloading of container ships in container terminals, a stowage plan of a ship cargo compartment to be handled by a container crane is transmitted from a harbor-side master computer via a data link to a PC of a crane automation system which renders the container crane operative in response to the stowage plan for transporting containers between a container ship and a repository location in a container storage area of the container terminal. The stowage plan is displayed on a touch screen of the crane automation system, whereby a next following repository location to be handled in the stowage plan is indicated on the touch screen, e.g. through a change in color.

摘要:
The stopping of a load suspended from a crane requires a swing control or, respectively, a swing damping. Upon employment of microwave measuring units, spacings between a carrying cable suspension and a load suspension point are determined on the basis of transit time measurements. The position of the load suspension point can be determined from the transit time measurements quickly and with high precision. Swinging motions are avoided by controlled opposing control of the carrying cable suspension.

To be able to acquire pendulum oscillations in the case of cranes with a high degree of accuracy, a marking having a reflecting surface is disposed in the area of the load. Mounted on the crane are both lighting equipment directed at the marking as well as a line-scanning camera that is likewise directed at the marking and that has an image-sensor linear array. The image-sensor linear array is aligned longitudinally to the direction of swing (x). Its signal is evaluated in an evaluation device to determine the instantaneous position of the marking.
